I've only used flannel once, I prewashed, then learned to my dismay that Joann's flannel leaves something to be desired. It was printed on the fabric crooked and it shrunk crooked and it looked a little faded and tired even though it was 'hot' cheery pastels. I used it anyway, not knowing any better as it was a baby quilt and bound to wear anyway, and I had never heard of an LQS or found this Board! I was in the dark!
